    • A method for the inspection of a circuit board, capable of precisely detecting deviation in position between the electrodes to be inspected of a circuit board and the inspection electrodes of a tester, thereby achieving fine alignment between the two, with high reliability. The method includes repeating, in two different axial directions, the measurement of conduction state between the electrodes to be inspected of a circuit board and the inspection electrodes of a tester each time changing, by a small distance, the relative position of the inspection electrodes portion of the tester and the circuit board, to detect a position of high conduction state and two positions of low conduction state which are distant from the position and located so that the position is held between them, in each of the two directions. From the information thus obtained, determining the desired connection position in which the inspection electrodes are to be in the highest conduction state in relation to the electrodes to be inspected in one or both of the directions. And then, moving the inspection electrodes portion relatively to the circuit board to place the inspection electrodes in the desired connection position.
    • 一种用于检查电路板的方法,其能够精确地检测待检查的电极与测试仪的检查电极之间的位置偏差,从而以高可靠性实现两者之间的精细对准。 该方法包括在两个不同的轴向方向上重复测量电路板的待检测电极与测试仪的检查电极之间的导通状态,每次每隔一段距离改变检查电极部分的相对位置 的测试器和电路板,以检测远离位置的高导通状态和低导通状态的两个位置并且被定位成使得位置保持在它们之间,在两个方向中的每一个方向上。 根据这样获得的信息,确定在一个或两个方向上相对于被检查电极的检查电极处于最高导通状态的期望的连接位置。 然后,将检查电极部分相对于电路板移动,以将检查电极放置在期望的连接位置。

    • A hydraulic punching machine is disclosed which has a casing having formed therein a piston chamber in which a piston is reciprocably mounted to define a pair of opposed fluid chambers, and a fluid reservoir for containing a hydraulic fluid. The piston has a piston rod carrying a punch for movement into and out of engagement with a die on the casing. Also mounted to the casing is a motor driven pump for pressurizing the fluid. A solenoid actuated spool valve alternately places the fluid chambers in communication with the pump and with a fluid drain. The solenoid is connected to an electric control circuit capable of sensing the extension and contraction of the piston rod. Therefore, upon extension of the piston rod, with the consequent creation of a punch in the work such as sheet steel, the control circuit cases the spool valve to automatically contract the piston rod under fluid pressure.
    • 公开了一种液压冲孔机,其具有在其中形成有活塞室的壳体,其中活塞可往复运动地安装以限定一对相对的流体室,以及用于容纳液压流体的流体储存器。 活塞具有承载冲头的活塞杆,该冲头用于移动进入和脱离与壳体上的模具接合。 还安装到壳体上的是用于对流体加压的马达驱动的泵。 电磁致动滑阀交替地将流体室与泵连通并且具有流体排放。 螺线管连接到能够感测活塞杆的伸缩的电气控制电路。 因此,在活塞杆延伸时,随着在钢板等工作中产生冲头,控制回路使滑阀将流体压力下的活塞杆自动收缩。

    • A coordinate input apparatus for detecting a coordinate position on the basis of a signal detected by a coordinate designator which can freely point on an input surface in which a plurality of conductors are embedded in parallel to each other, the conductors constituting in combination a main loop to which scaning signals are supplied sequentially. A compensating loop which is composed of a conductor is provided in the vicinity of a common conductor of the main loop separately therefrom such as to surround the main loop. A constant current is delivered to the compensating loop in the reverse direction to that flowing on the main loop to mitigate the magnetic field produced by a common conductor. A compensationg value which corresponds to the approximate position of the coordinate designator is called from a first storing means to calculate the interpolating value thereof. A correction value for correcting the error between the interpolating value and the actual position of the coordinate designator is called from a second storing means in order to specify the position pointed by the coordinate designator on the basis of the interpolating value and the correction value.
    • 一种坐标输入装置,用于根据由坐标指示器检测到的信号来检测坐标位置,所述坐标指示器可以自由地指向彼此平行地嵌入多个导体的输入表面,所述导体构成主循环 依次提供扫描信号。 由导体构成的补偿回路与主回路的公共导体的附近分开设置,以包围主回路。 恒定电流以与在主回路上流动的方向相反的方向输送到补偿回路,以减轻由公共导体产生的磁场。 从第一存储装置调用对应于坐标指示符的近似位置的补偿值,以计算其内插值。 从第二存储装置调用用于校正内插值与坐标指示符的实际位置之间的误差的校正值,以便根据内插值和校正值来指定坐标指示符指出的位置。
